Wedding bells may take on a very different tone for Chicago couple Jared Milrad and Nate Johnson if one guest on their list decides to attend.

Milrad and Johnson say they sent the Twitter initiation as a way for the couple to return a favor. They’re including the Democratic presidential candidate in their celebration after she included them in her 2016 campaign launch video.

Right now, Johnson and Milrad are planning a small July 19 wedding at Montrose Harbor. Clinton’s appearance could change that dynamic. They got an RSVP, of sorts, from Clinton’s campaign manager who called the invite a nice gesture. Attendance TBD.

The couple will send Clinton a paper “save the date” as they wait and see.

“We’d love to have her come, maybe have her on the dance floor for a dance,” Johnson said.
